Abstract: a reinforced elongate element (12) comprises a core (22) of elongate shape covered by at least one layer (33) of composite material comprising a plurality of tapes (32) wound at a settable winding angle around said core (22), each of the tapes (32) being made using glass or carbon threads or fibers (35) embedded in a matrix (34) of thermoplastic resin. The elongate element may be in the form of very long tubes suitable for use off-shore.

Abstract: A brake disc of carbon-carbon composite material comprising a substrate of a mixture of carbon fibres of two very different ranges of length and embedded in a carbon matrix. The longer fibres are oriented and distributed randomly in planes approximately parallel to the friction surfaces of the disc, and the shorter fibres are oriented and distributed randomly in the volume of the disc. The brake discs according to the invention are useful in particular in the aviation field. They can be made by ultrasonically molding a mixture of the fibres and a suitable liquid, followed by heat treatment; or by chemical deposition of carbon from the vapor phase.
